Variable Power Supply Power Supply is a useful device to those who put their first step in electronics. There are two types of Power Supplies: • Constant Voltage Power Supply • Variable Voltage Power Supply In constant Voltage Supply we get constant volt at output while in variable power supply we can’t vary voltage at output. Here in this topic we cover only Variable Voltage Power Supply. What is Variable Voltage Power Supply? A power supply is an electrical device that supplies electric power to an electrical load. A variable power supply is one which includes some means for the user to easily adjust the output voltage. Adjustment is most often accomplished with a potentiometer, through which you can control the output voltage What Material Required to make this project? • LM317 Voltage Regulator IC • 12k and 220ohm Resistance • 6x 1n4007 Diode • 0.1uf and 470uf, 25v and 10uf, 50v Capacitor • 10k Potentiometer • 24-0 Transformer
